Jettara was a fan created character based on the popular 1980's cartoon series, Transformers. She was the first female Sweep and later moved on to be a main character in the fan made comic book Bloodlines that followed Transformers: Beast Wars.

In 2001 Jettara went through another transformation and left the world of Transformer fandom (although she still still popular among many TF fans and still inspires interest in that genre) to become a main character in numerous urban fantasy novels from the Raven's Realm series and more recently the new Women of Ravenwood series available through eXtasy Books.

In all incarnations, Jettara has alway meant Banshee or she how could see death.

A buzz word being used to refer to creators and influencers forming or encouraging unhealthy relationships with their fans. Usually used in the context of young audiences feeling they have a relationship with the influencer due to the huge amount of the influencer’s content they consume. The influencer in question, however, is unaware of the fan’s existence other than the general knowledge of having fans. Common examples include Dream and his stans. These relationships are exacerbated by the influencers confirming they have more than a creator-to-viewer relationship.

The word is circulating due to various YouTube essays about the phenomenon using the word, and therefore people who enjoy complaining about influencers repeating what they heard in the video in any comments section they can find.
